But, when separated, Vadd and/or 5V is supplied normally.
If this is the case, check each connectors connection. (Check if there isn t any extraneous
material between the Connector pins. Check whether cables and FPC are correctly connected)
Check the chip resistance(four parallel connected 47 ohm ) located left and right of each PC
1~7 of CONN-LEFT/RIGHT PCB to see if open/short circuit..
If all above are normal, unscrew DATA COF and observe DIODE TESTER.
